Unfortunately not. I have the same problem and the same solution here. 
You really have to do a restart of asterisk. I think the reason that 
asterisk does not always lookup the IP Adress for the DDNS-Hostname is 
performance. But it would be nice if a sip reload could do so. 
Has anybody contacts to the developers ;-) ?
